Quoting chrischilderhose,
I have the same issue on version 2.08 of this issue. I reported it in the feedback thread for that release but similar problem where it will show stuff I open then after a while it goes blank. There is a ton of files in my recent list too.
Windows 11 - 24H2 (OS Build 26120.461)

This issue is still happening where there will be recent files/folders listed, and gradually, over time, it clears out. Is there going to be a permanent fix for this?
Windows OS Build - 26120.3073 (Beta Channel)
Start 11 - 2.52
When I click the Start11 menu and click the Windows Menu link, the recent files show there, so I'm not sure why that one works, and this one clears itself out gradually, as shown in the screenshot.
